I have a C drive and H drive, what is H?

The short answer is that the hard drive in your computer is compressed. Compressing a computer hard drive allows you to fit more information on a drive, but requires an area (known as H partition) to be created for files that will not work while compressed.

Note: The H drive is the portion of the hard drive that is not compressed.

Can I remove H safely?

Compressing the hard drive is usually permanent and although it can be possible un-compressed the drive it often causes more problem than its worth. If you want to only have a C: drive or if you are running into issues with your hard drive compressed we recommend you erase your computer and start over.
